Data related to presentation, histopathology, prognosis and treatment of DCIS were gathered from 48 women from the Asian Breast Cancer Database at the Nightingale Centre, all of whom had begun with an initial diagnosis (at biopsy) of DCIS. These were compared with age-matched Caucasian patients, also diagnosed with DCIS at the time of biopsy. The total study included 96 patients.

Asian women presented with a larger tumour size, more progressed to a diagnosis of invasive carcinoma, and more had mastectomies compared to Caucasian women. Since fewer Asian women are presenting via the screening programme, education and awareness of breast cancer and screening needs to be increased in Asian women to increase their screening uptake rates.
